An object is moving in a straight line from a fixed point. The displacement s(in meters) is given by s=-2t^2+28t+45, t is greater than or equal to 0, where t is in seconds. 1...

Ball A, with a mass of 20 kilograms, is moving to the right at 20 meters per second. At what velocity should ball B, with a mass of 40 kilograms, move so they both come to a standstill upon...

It's a numerical of physics of chapter motion please solve it .

Jacob kicks a soccer ball off the ground and into the air, with an initial velocity of 33 feet per second. Using the formula H(t) = -16t + vt + s, what is the maximum height the soccer ball...

a.) find v(t), the vertical velocity of the ball at time t. Give units b.) find v(1) and explain what is happening to the ball at this time. What is the height of the ball at this time? c...

Determine the average of this 42.2km race. Express your answe in both m/s and km/h. ans.(3m/s, 10.9km/h)

h=-16t2+vt+s

How do I graph this my x scale has to go by .25 so what is my y coordinates(h vs t)(h-x vs t-y) i also need to know what the equation for this problem would be

James is lying on his body board out in the surf. 12 waves pass him every minute. These waves are about 14m apart from one crest to the next and they rise 2 meters above the normal water level. a)...

On a very wet and slippery rugby field a 120 kg halfback tackles a 90 kg second rower. Prior to the collision the halfback is slipping with a velocity of 5.6m/s south and the second rower is sliding...

A car of 1 tonne travels at a speed of 100km/h collides with a 3 tonne van travelling 20km/h in the same direction. After the collision the car rebounds at 20km/h. Calculate the impulse on the van...

A small car of mass 500kg is travelling at 120km/h when it hits stationary truck (of 1.5 tonne mass) head on. The small car rebounds and travels in the opposite direction at 40km/h. The collision...

A car (m=900kg) travelling at 70km/h hits a pedestrian (m=60kg) who is travelling at 1m/s in the same direction. After the collision the car has a velocity of 30km/h in the same direction it was originally...

The total mechanical energy of an object with mass mm at height hh in a closed system can be written as ME = 12mv2 + mghME = 12mv^2 + mgh. Solve for v, the velocity of the object, in terms...

A sail boat is traveling north at 10 km/h, relative to the water. The water is flowing north at 5 km/h. What is the velocity of the boat to the ground? What is the equation needed???

This is a science/math problem. I'm pretty sure I have to convert the minutes to hours, but I don't know what to do with the kilometers then. I need clarification and steps to show me what I need...

A projectile is fired vertically with an initial velocity of 560 feet per second. The distance s in feet above the ground after t seconds is given by the equation s=−16t^2+560t. For what range...

Anissa rides her snowboard down a hill sloped at 25 degrees. The coefficient of kinetic friction between her snowboard and the snow is 0.15. If Anissa's mass is 55 kg, how fast is she going 7 seconds...
